We have been testing INUPATHY on more than 200 dogs so far.
Here are some of the user’s voice.
We will keep on testing and improving.
Ever since being aggressively barked at a play ground, I thought that my dog felt uneasy at play grounds. With INUPATHY, I discovered that my dog feels happiness in various situations, and I realized that I have been over-protective. Now we go out more often, and I enjoy every day even more.
Female, 30's, Dog type : Toy poodle
I was worried that my children were handling our dog too roughly, but after I told my children that "Green color means the dog is relaxed", they paid more attention to the response of the dog, and handled him more gently. I was happy to see my children trying to figure out how to make better relationship with our dog.
Male, 30's, Dog Type : Welsh corgi cardigan
The response of INUPATHY was just as I expected from the expression and behavior. One thing that I discovered, was that she was happy during walks. I'm so glad to see this, and I love her even more.
Male, 40's Dog Type : Japanese Spitz
